Application of Slewing bearing

A slewing bearing, also called a turntable bearing, is a type of bearing that allows for a heavy but slow-turning or slowly-oscillating load to be supported in combination (axial, radial and moment loads), often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis (yaw) windmill. In other orientations (e.g. a horizontal axis of rotation) they are used in materials handling grapples, forklift attachments, welding turnover jigs and so on.

Slewing rings range in size from as little as 100mm diameter to well over 15 000mm (often segmented at this size for easy transport and handling); for example the bearings on the Falkirk Wheel are 4 meters diameter and fit over a 3.5 meter axle. Slewing bearings are often made with gear teeth integral with the inner or outer race (or both in rare cases) used to drive the platform relative to the base (for example in winches).

Slewing rings are used in a variety of applications, including:

• Wind turbines: Slewing bearings are used in wind turbines to support the nacelle and rotor blades.
• Cranes: Slewing bearings are used in cranes to support the boom and jib.
• Drilling rigs: Slewing bearings are used in drilling rigs to support the mast and drill string.
• Robotics: Slewing bearings are used in robotics to support the manipulator arm.
• Machine tools: Slewing bearings are used in machine tools to support the spindle and workpiece.

Slewing bearings are a critical component in many applications. They are responsible for supporting heavy loads and allowing for smooth and precise movement.
